Back in 2012, Aldean, 37, was caught on camera kissing American Idol alum Kerr at a bar in West Hollywood. The "Night Train" singer apologized for the incident on Facebook immediately after, admitting that he "screwed up." "I had too much to drink, let the party get out of hand and acted inappropriately at a bar," he wrote at the time. "I left alone, caught the bus to our next show and that's the end of the story."

Aldean and Ussery, his wife of nearly 12 years with whom he has two daughters, tried to make their marriage work after the scandal. However, seven months after the incident, Us broke news that Aldean separated from Ussery, and filed for divorce shortly after.

"This is a really tough time for my entire family," Aldean told Us in a statement at the time. "Jessica and I have been together since we were teenagers. We've been through a lot of ups and downs over the years as we grew up together as a couple. She will always be important to me because she is the mother of my children, and I know that we will both always make our daughters our No. 1 priority."
